construction and arrangement hereinafter de- .scr1bed, and pointed-out in the-claim.

In the drawings, Figurel is au elevation of a window struct-ure, showing my shutter-fastener in operation; and Fig. 2 is a section on line 2 2 of Fig. l looking in the direction of the arrow. Figs. 3 and 4 are details of the bracket and catch, respectively.

In the drawings, A represents the sill of a window-frame,and B a shutter hinged to the frame and adapted when opened to be swung to a position close against the wall in the usual manner of outside shutters. f

C indicates my improved fastener as a whole. rlhe same consists, essentially, of but two members, a bracket and a catch or fas'- tening-lever supported by said bracket, each of said members being formed of a single piece of metal. The bracket member 3 preferably consists of a plate having a central raised portion 4 and Hat ends 5 5, the webs connecting said end and middle portions being slotted, as at 7, for the reception of the lever 8. Said lever 8 consists of a ilat thin bar straight throughout a portion of its length, as

. shown at 9, and then curved upward, as at longer and heavierthan the curved and bent portions 10 and 11, the pivotal point of the lever being at approximately the juncture ot' the curved and straight portions. The lever Ais thus unbalanced, the weight of the inner end normally maintaining the outer orcatch end in raised position.

The lever and bracket are provided with registering apertures to receive a pivot pin or screwlZ, and the.` bracket carriesta suit.,y able lug or projectionl, adapted to-act as ay stopk to limit the;upwardg,movement ofthej outer curved en'dof `thelever.l

In assembling the parts'the bracketis sel: cured i-n any desired manner, y.asbysc z'rews,: to the window-sill andthe lever-pivotally( mounted therein, as'` shown. The weightof the lstraight end of theflevermaint'ains the. f f curved end constantly raised andin-c'ontact A with the stop '13',in whichpositionitsndownLV f wardly and outwardly inclined end lies inthe"k v path of the lower edge,oftlie shutterr The operation isob'vious.V Whentheshutter is opened,`its 4 loweredgey coming in con-y ,7b tact with the inclined portion 11 of the lever Y f forces theouter end of the latter downward and passes behind the same. The weight'of theinuer end oi' the lever then restores the outer end to raised position, where it serves as av catch to securethe shutter in open position in the manner'illustrated in Fig. l.

When it isdesired to'close'the shutter, the straight end of the lever is lifted and thev outer end thereby' depressed lto release the4 shutter. v

Having thus described my in'vention,`what,

In a window-shutter fastener, the combina-` tion of a bracket, 3,'secured to the windowsill, said bracket having depressed ends 5, and y' a raised central-portion'f,` and an integral stop 13; and an unbalanced lever 8 pivotally y mounted between the portions 4: and 5 of the bracket formed of a single lat"metallic strip having a straight innerlend, 9, a portion l0,

beyond the pivot'curved upwardly in the direction of its width, and an outer-end porv tion, 1l downwardly inclined in a plane transverse to the width ofthe lever, said lever being arranged with its straight portion extendfv ing to substantially the middle of the windowv GEORGE P. RAHN.
